Automobile Damping and Silencing Sheet DC40-01C1

Short Description:

The automobile damping and silencing pad is a vital accessory that reduces noise during braking. Positioned on the brake pad’s steel backing plate, it absorbs vibrations and noise caused by friction between the brake pad and rotor. The brake system comprises the brake lining (friction material), steel backing plate, and damping pads. These pads disrupt sound waves, preventing resonance and phase interference, which amplifies noise. By minimizing vibrations and noise, damping pads enhance driving comfort, improve braking efficiency, and protect brake components from wear.

Products Description

The automobile damping and silencing pad is an accessory used to reduce or eliminate the noise during brak-ing. It is an important component of the automobile brake pad. It is arranged on the steel back of the brake pad. When the brake pad is braking,it plays a certain damping effect on the vibration and noise caused by the brakepad pad pad. The brake system is mainly composed of brake lining (friction material), steel back (metal part) and damping and silencing pads.

Silencing principle: brake noise is generated by friction vibration between friction plate and brake disc.The in-tensity of the sound wave will change once from the friction lining to the steel back, and once again from thesteel back to the silencing plate.The phase resistance of layers and the avoidance of resonance play a role inreducing the noise.
